  • FDA unveils open source code for collecting patient data

    Apps and devices are everywhere. 2018 appears to be the year of voice technology pilots in healthcare. Medical data is exploding.

    Late last month at the HIMSS Connected Health Conference in Boston, in fact, it became evident that the market is so flooded with apps, devices, wearables and wellness tools that what’s needed is radical simplicity, if only so clinicians and consumers can better grasp their options.

    Despite all the technologies available, there is not yet a seamless way to tie patient-generated health information into larger datasets.

    The MyStudies code is neither intended to solve that problem entirely nor is it something many patients are likely to pick up on their own. Indeed, it’s too early to know how developers or researchers will use the code but they now have the technological underpinning to at least start integrating even small data sources.

  • The Influence of an Open Source Artificial Pancreas System

    Twitter data indicate that patient-driven innovation in diabetes management has resulted in a patient population with type 1 diabetes who choose to build and share knowledge around a do-it-yourself (DIY) open source artificial pancreas system (OpenAPS). OpenAPS is an open and transparent effort to make safe and effective basic artificial pancreas system technology widely available to anyone with compatible medical devices who is willing to build their own system.

    In a study published in the Journal of Diabetes Science and Technology, Michelle L. Litchman, PhD, FNP-BC, FAANP, and colleagues examined Twitter posts (with the hashtag #OpenAPS) to understand how patients, caregivers, and care partners perceive OpenAPS, the personal and emotional ramifications of using OpenAPS, and the influence of OpenAPS on daily life.“There is a distinct difference between diabetes management by a textbook and diabetes management in real life,” says Dr. Litchman. “We sought to understand how people with diabetes manage their condition in the real-world as it relates to OpenAPS.”

Intel's Gallium3D Driver Is Running Much Faster Than Their Current OpenGL Linux Driver With Mesa 19.3

Last month I did some fresh benchmarks of Intel's new open-source OpenGL Linux driver with Mesa 19.2 and those results were looking good as tested with a Core i9 9900K. Since then, more Intel Gallium3D driver improvements have landed for what will become Mesa 19.3 next quarter. In taking another look at their former/current and new OpenGL drivers, here are fresh benchmarks of the latest code using a Core i7 8700K desktop as well as a Core i7 8550U Dell XPS laptop. This month so far Intel's new Gallium3D OpenGL driver has seen OpenGL 4.6 support added, an optimization to help the Java OpenGL performance (one of the deficiencies noted by our earlier rounds of benchmarks), and other performance work. For some weekend benchmarking fun I tested the Core i7 8700K desktop and Dell XPS 13 laptop with Core i7 8550U graphics while comparing the OpenGL driver options. The driver state for both the i965 and Iris Gallium3D drivers were of Mesa 19.3-devel Git as of this week and also running with the near-final Linux 5.3 kernel. Read more

Databases: MariaDB, ScyllaDB, Percona, Cassandra

  • MariaDB opens US headquarters in California

    MariaDB Corporation, the database company born as a result of forking the well-known open-source MySQL database...

  • ScyllaDB takes on Amazon with new DynamoDB migration tool

    There are a lot of open-source databases out there, and ScyllaDB, a NoSQL variety, is looking to differentiate itself by attracting none other than Amazon users. Today, it announced a DynamoDB migration tool to help Amazon customers move to its product.

  • ScyllaDB Announces Alternator, an Open Source Amazon DynamoDB-Compatible API

    ScyllaDB today announced the Alternator project, open-source software that will enable application- and API-level compatibility between Scylla and Amazon’s NoSQL cloud database, Amazon DynamoDB. Scylla’s DynamoDB-compatible API will be available for use with Scylla Open Source, supporting the majority of DynamoDB use cases and features.

  • ScyllaDB Secures $25 Million to Open Source Amazon DynamoDB-compatible API

    Fast-growing NoSQL database company raises funds to extend operations and bring new deployment flexibility to users of Amazon DynamoDB.

  • ScyllaDB Announces Alternator, an Open Source Amazon DynamoDB-Compatible API

    ScyllaDB today announced the Alternator project, open-source software that will enable application- and API-level compatibility between Scylla and Amazon’s NoSQL cloud database, Amazon DynamoDB. Scylla’s DynamoDB-compatible API will be available for use with Scylla Open Source, supporting the majority of DynamoDB use cases and features.

  • ScyllaDB powers up Alternator: an open Amazon DynamoDB API

    Companies normally keep things pretty quiet in the run up to their annual user conferences, so they can pepper the press with a bag of announcements designed to show how much market momentum and traction that have going. Not so with ScyllaDB, the company has been dropping updates in advance of its Scylla Summit event in what is perhaps an unusually vocal kind of way. [...] Scylla itself is a real-time big data database that is fully compatible with Apache Cassandra and is known for its ‘shared-nothing’ approach (a distributed-computing architecture in which each update request is satisfied by a single node –processor/memory/storage unit to increase throughput and storage capacity.

  • Percona Announces Full Conference Schedule for Percona Live Open Source Database Conference Europe 2019

    The Percona Live Open Source Database Conference Europe 2019 is the premier open source database event. Percona Live conferences provide the open source database community with an opportunity to discover and discuss the latest open source trends, technologies and innovations. The conference includes the best and brightest innovators and influencers in the open source database industry.

  • Thwarting Digital Ad Fraud at Scale: An Open Source Experiment with Anomaly Detection

    Our experiment assembles Kafka, Cassandra, and our anomaly detection application in a Lambda architecture, in which Kafka and our streaming data pipeline are the speed layer, and Cassandra acts as the batch and serving layer. In this configuration, Kafka makes it possible to ingest streaming digital ad data in a fast and scalable manner, while taking a “store and forward” approach so that Kafka can serve as a buffer to protect the Cassandra database from being overwhelmed by major data surges. Cassandra’s strength is in storing high-velocity streams of ad metric data in its linearly scalable, write-optimized database. In order to handle automation for provisioning, deploying, and scaling the application, the anomaly detection experiment relies on Kubernetes on AWS EKS.
